About this gig
Need to add AI to an existing application without rebuilding your product?
I integrate OpenAI, Google Gemini, Groq, and other documented AI APIs into SaaS products, web apps, and backend systems.
I CAN HELP WITH
OpenAI, Gemini, or Groq API integration AI chat and assistant features Structured JSON outputs Summarization and classification Database-connected AI workflows Multi-provider routing and fallbacks Secure API-key configuration Error handling, testing, and deployment support
You receive one clearly scoped AI feature, clean source code, validation and error handling, configuration notes, and a concise handoff.
I built Dervale, a production-oriented multi-tenant AI gateway using Spring Boot, React, PostgreSQL, Redis, and Docker. It includes multiple AI providers, routing, authentication, usage controls, and request logging.
Packages cover one bounded integrationnot a complete SaaS platform or unlimited workflows. Larger RAG, agent, or multi-module requirements are scoped separately.
Send me the AI workflow you want to add and your current stack. I will confirm the cleanest integration approach and correct package before you order.
